Novel solar drying system

Abstract

The invention discloses a novel solar drying system. The novel solar drying system comprises a solar air heat gatherer, an air blower, a solar battery, a drying box, a temperature and humidity controller, a valve and a heat exchanger. The novel solar drying system is characterized in that the heat exchanger is provided with a first air inlet, a second air inlet, a first air outlet and a second air outlet; an insert pipe is arranged in each vacuum heat gathering pipe of the solar air heat gatherer, and the insert pipes are connected with an air buffer backflow zone header after passing through the top of a hot air flow passage zone header; the air blower is arranged between the air outlet of the heat gatherer and the air inlet of the drying box; an air flow passage zone is arranged in the side of the inside of the drying box near the air blower, and a material drying zone is arranged at the other side; an induction probe of the temperature and humidity controller is arranged at the air outlet of the drying box; an air return pipeline led from the air outlet of the drying box is divided into two branches, one branch is connected with the first air inlet of the heat exchanger through a second valve, the other branch is further divided into two passages after passing through the first valve, one passage is directly connected with the air inlet of the heat gatherer header, and the other passage is connected with the first air outlet of the heat exchanger through a third valve.

Description

technical field [0001] The invention relates to a novel solar drying system, which belongs to the technical field of solar heat utilization. Background technique [0002] With the development of science and technology, human beings consume more and more energy, but as far as the current situation is concerned, some traditional energy sources such as coal, oil, and natural gas will cause certain environmental pollution, and these traditional energy sources are slowly drying up Therefore, it is necessary to seek new energy sources to replace these traditional energy sources. As a new energy source, solar energy has been widely recognized and developed rapidly. As an important branch in the field of solar thermal utilization, solar drying has replaced traditional drying with its advantages of no pollution, energy saving, sanitation, and convenience, and has become a key research project at home and abroad. one. Solar drying is the oldest and most widely used form of human uti...

Problems solved by technology

Moreover, most of the solar drying systems currently involved are open systems, that is, the air discharged from the drying chamber directly enters the atmosphere, which makes most of the useful heat in the discharged humid air not effectively utilized; Humid air also directly enters the drying room without dehumidification treatment, so that the moisture content of the air in the drying room does not decrease, not only failing to achieve the purpose of drying, but on the contrary, it will affect the entire drying process, so the efficiency has not been greatly improved Improvement; very few solar drying systems dehumidify the discharged humid air and then re-enter the drying system, but the dehumidification device is too complicated, which increases the drying cost
